I was just coming on to say just the same.My recommendation is don't do it.
One of the advantages of separate belts is that you rarely lose em all, and you have a better chance of getting where you're going without consequences when one of 3 or 4 belts break, but when your only belt goes you're screwed.
On my older stuff I've lost 1 of my alternator belts but there was a 2nd one. Or my ps belt or when my alternator belt went I still had one pulling my water pump so I wouldn't overheat.
I get cars towed in all the time that people can't steer, they run the battery dead, AND they overheat because they blew the only belt the car has....
